Wow... I had not realized this until I saw your post, Paashaas. 

A bit strange for me, because of the way that I have been changing around my buy orders in recent times... Actually historically, some members here might remember that last year I had buy orders down to about $9k, but in recent times, I had considered ONLY maintaining buy orders down to the 208-week moving average, which is nearly $17k, but even based on my own moving around of values and even spending some my value, I have only kept buy orders down to $24k and on that particular exchange, I had only maintained buy orders down to $42k  (which started at $60k) - so all of my buy orders on that exchange (about 17 of them were filled between $42k and $60k).. cannot really complain... except such surprise filling of all of those orders did cause me to have to reset a number of orders and to consider how I was going to treat this whole matter in order to attempt to get my systems rebalanced... and yeah did mess me up in terms of further overallocating into BTC by filling those extra orders.. but who is going to complain about a discount - when considering spot price, right?
